Several Major League Baseball teams have a tradition of hazing their rookie players every year by forcing them to dress up as women for team flights, and now, a powerful LGBT group aligned with pro athletes is calling on that tradition to stop!

Players on the teams — which include the Oakland Athletics, Miami Marlins, Chicago Cubs, and many others — contend that the event is harmless fun designed to lightly haze rookies while promoting team bonding.

Athlete Ally, the LGBT group, sees it differently, and they are worried the cross-dressing players are sending the wrong message to kids.
